Mean Result. 
Position 86° 4 6' nf( 10 Obs.) ; Epoch 1825.05 ; 
Distance 35". 678 (15 Obs.) ; Epoch 1825.06. 
By a mean of two measures in 1783, the position comes 
out for that epoch 85 0 24/ differing but i° 22' from the pre- 
sent. The distance at the beginning of 1783 was 29". 30, 
and the measure is called very exact ; yet an increase of 
distance to the extent of 6". 38 is beyond probability, a cir- 
cumstance which proves the occasional occurrence of the 
micrometrical error already pointed out, even in distances so 
low as 3 o' 7 . (H.)
